Abstract

The utility model relates to a forklift mast. Including outer mast and interior portal, interior portal on be fixed with the roller shaft, the roller shaft on the cover be equipped with the gyro wheel, the roller shaft include with rollers matching's first shaft part, positioning roller's second shaft part and with interior portal mutually fixed third shaft part form, first shaft part be the hollow shaft. According to the above technical scheme, the utility model discloses set the roller shaft to hollow structure, when radial load was too big, the roller shaft can realize that the gyro wheel and the self -adaptation of outer mast contact through elastic deformation like this to can offset partlyly because of the linear cutting that straightness caused of hanging down of the welding on the portal including the roller shaft, hollow design simultaneously makes its characteristic that has the elastic axis, in the time of can absorbing partly portal and rise to rise the goods can the stroke, make the portal rise to rise and have more the stationarity.

Description

Forklift door frame
Technical field
This utility model is related to fork truck field and in particular to a kind of forklift door frame.
Background technology
At present, the operation principle of forklift door frame is welding roll axle on inner upright mounting, roller shaft is set with roller, by interior Gap adjustment between door frame and outer mast, makes in the stable internal arm being nested in outer mast of inner upright mounting, in the effect of external force Under, linear reciprocating motion is done in the direction that inner upright mounting can limit along outer mast.In actual moving process, often occur that roller is cut Cut the phenomenon of outer mast, it shows as, and metal wire-drawing in the place that outer mast contacted with idler wheel surface, steel plate has cut, metal " peeling ", ultimately results in long-time (about one year about) after using, the shelves of opening of outer mast become large-sized, and roller is because of itself material Its hardness of matter and PROCESS FOR TREATMENT is high, and size is almost unchanged, and the fit clearance that this allows for roller and outer mast is opened between shelves becomes big, Thus leading to inner upright mounting in up and down motion landing goods, producing in outer mast and rocking, cause to jolt seriously during goods landing, Noise becomes big and produces potential safety hazard.Cost because changing outer mast is too high, so common solution is to change larger chi Very little roller is to fill up the gap between roller and door frame.
Utility model content
The purpose of this utility model is to provide a kind of forklift door frame, this forklift door frame can avoid outer mast and roller it Between cutting.
For achieving the above object, this utility model employs technical scheme below: include outer mast and inner upright mounting, described Roller shaft is fixed with inner upright mounting, described roller shaft is arranged with roller, described roller shaft includes matching with roller First shaft part, the second shaft part of positioning roller and threeth shaft part fixing with inner upright mounting phase form, and the first described shaft part is Hollow axle.
The periphery of described first shaft part is provided with circlip groove.
Described outer mast is made up of channel-section steel front wing panel, channel-section steel rear fender and channel-section steel web, described channel-section steel front wing panel And the end face that channel-section steel rear fender is matched with roller is Non-smooth surface plane.
The overcoat of formed interference fit is arranged with the wheel face of described roller.
As shown from the above technical solution, roller shaft is arranged to hollow-core construction by this utility model, so in radial load mistake When big, roller shaft can be realized roller by elastic deformation and be contacted with the self adaptation of outer mast, such that it is able to offset a part of because The linear cutting that welding perpendicularity on inner upright mounting for the roller shaft causes;Simultaneously hollow design makes it have the spy of elastic shaft Property, energy impact during a part of door frame raising goods can be absorbed, make door frame raising have more stationarity.
Brief description
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of roller shaft in Fig. 1;
Fig. 3 is the structural representation of this utility model embodiment one;
Fig. 4 is the structural representation of outer mast in embodiment one;
Fig. 5 is the structural representation of this utility model embodiment two.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further:
A kind of forklift door frame as shown in Figure 1 and Figure 2, including outer mast 1 and inner upright mounting 2, inner upright mounting 2 is fixed with roller Axle 3, roller shaft 3 is arranged with roller 4, and roller shaft 3 includes the first shaft part 31, the second axle of positioning roller matching with roller Section 32 and threeth shaft part 33 fixing with inner upright mounting phase form, and the first shaft part 31 is hollow axle, the periphery of the first shaft part 31 It is provided with circlip groove 34.Roller shaft 3 is arranged to hollow-core construction, so when radial load is excessive, roller shaft can pass through bullet Property deformation realize roller and contact with the self adaptation of outer mast, such that it is able to offset part welding on inner upright mounting because of roller shaft The linear cutting that perpendicularity causes;Simultaneously hollow design makes it have the characteristic of elastic shaft, can absorb a part of door frame and rise Rise energy impact during goods, make door frame raising have more stationarity.
Embodiment one:
As shown in Figure 3, Figure 4, outer mast 1 is made up of channel-section steel front wing panel 11, channel-section steel rear fender 12 and channel-section steel web 13, groove The end face that steel front wing panel 11 and channel-section steel rear fender 12 are matched with roller 4 is Non-smooth surface plane.
The present embodiment is on the basis of hollow roller axle, by channel-section steel front wing panel 11 and channel-section steel rear fender 12 and roller 4 phase The end face of cooperation is arranged to Non-smooth surface plane, after the plane of Non-smooth surface with roller forced contact, so that the surface of Non-smooth surface is obtained To Fast Wearing and deforming tops, the surface of abrasion and the part of crimp, in the presence of frequent rolling power, its surface is hard Degree is strengthened it is achieved that the very stiff and demanding structure in hard idler wheel surface and hard channel-section steel face, thus avoiding the cutting phenomenon to channel-section steel face.
Embodiment two:
As shown in figure 5, the overcoat 5 of formed interference fit is arranged with the wheel face of roller 4.
The present embodiment is on the basis of hollow roller axle, arranges overcoat 5, overcoat 5 and roller 4 on the wheel face of roller 4 Between be interference fit, so do not need extra clamp device, the strong adaptability to narrow working space;When roller and external door When contact gap between frame becomes big, directly change overcoat, reduce production cost, change also more convenient simultaneously.
Embodiment described above is only preferred implementation of the present utility model to be described, not to this practicality New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of this utility model claims determination In the range of.
